]GetBoundsInPixels(float, float)
Calculates the bounds of the shape in pixels for a specified zoom factor and resolution.
public Rectangle GetBoundsInPixels(float scale, float dpi)
| Parameter | Type | Description |
|---|---|---|
| scale | Single | The zoom factor (1.0 is 100%). |
| dpi | Single | The resolution (horizontal and vertical) to convert from points to pixels (dots per inch). |
Return Value
The actual (as rendered on the page) bounding box of the shape in pixels.
Remarks
This method converts BoundsInPoints into rectangle in pixels.
Examples
Shows how to measure and scale shapes.
